Description

at an angle to it in the plane perpendicular to the washing and cleaning organ.

The disadvantage of this design is the small surface of the working body and, therefore, insufficient capacity.

A device for washing and cleaning of root-and-vegetable crops is known, in the cylindrical body of which there are mounted upper and lower horizontally oppositely rotating discs forming between them a working chamber. The surface of the working ortan contacting the fruit to be processed is enlarged.

The disadvantage of this design is its considerable complication due to the introduction of a spiral-shaped guide element into the working chamber, as well as due to additional nodes providing the opposite rotation of the discs.

Closest to the present invention is a device for cleaning potatoes, consisting of a cylindrical body, the upper space of which forms a working chamber. The working chamber consists of two parts; the upper part is fixed, and the lower has the ability to rotate around the vertical axis. The surface of the working chamber is made of abrasive material: the fixed side surface is lined with abrasive segments, and the movable bottom is made in the form of a conical bowl of abrasive material, while the bowl has several waves on its lower part. The lower part of the body (under the working chamber) serves as a collection of waste. Water is fed through a nozzle at the top of the working chamber to flush out the cleaning products. The tubers are loaded through the upper window, and unloaded through the side hatch. The operating member is driven by an electric motor.

This device is inherent in the property of periodic clogging of abrasive surface cleaning products, which reduces the quality of cleaning tubers, requires additional time and reduces productivity. In addition, there are no smooth transitions between areas of the abrasive surface of the working chamber. This leads to additional shock loads on the tubers to be processed, i.e. injuring them. The time of contact of the tubers with an abrasive surface also decreases - the productivity of the device decreases. When the device is in operation, the tubers under the action of centrifugal forces move along the walls of the working chamber and then roll down. At this point, they also do not come into contact with the abrasive, i.e. not

cleaned up. It also increases cleaning time,

The aim of the invention is to increase the productivity of the device and improve the quality of the cleaned tubers.

The goal is achieved by the fact that a device for cleaning potatoes, comprising a housing inside which is a working chamber consisting of two

0 parts, the surface of which is made of abrasive material, the upper part is stationary, and the lower part is mounted for rotation, a fitting for supplying water to the working chamber and the loading window, provided with a water tank formed by the inner surface of the housing and the outer surface of the fixed part of the working chamber, at the same time the fixed part of the working chamber has through inclined

0 holes for the passage of water, and the inner surface of the working chamber has the shape of an ellipsoid.

In addition, it is advisable to provide the device with a core vertically mounted with the possibility of rotation on the lower part of the working chamber and made in the form of a truncated cone with an abrasive surface. -

The drawing is a diagram of the device, the cross section of the cross section.

The potato peeler consists of a cylindrical body 1 within which the upper fixed part 2 of the working chamber 3 and the bottom

5, the movable part 4 of the working chamber 3, the latter consists of a base 5 with a bowl 6 of abrasive material fixed on it. The upper part 2 of the working chamber 3 is formed by abrasive segments 7.

0 The abrasive surfaces of the bowl b and the upper part 2 of the working chamber 3 have the shape of an ellipsoid and smoothly join each other. A fitting 8 for supplying water to the tank is provided on the side surface of the housing 1.

5 9 formed between the housing 1 and the upper part 2 of the working chamber 3. On the axis of the lower part 4 of the working chamber 3 fixed core 10 in the form of a truncated cone with an abrasive surface. The segments 7 forming the upper part 2 of the working chamber 3 have a plurality of through inclined holes 11. In the upper part of the housing 1 there is a loading window 12.

The device works as follows.

Through the loading window 1G, the portion of potato tubers to be cleaned is poured into the working chamber 3. The lower part 4 of the working chamber 3 is rotated. Through the nozzle 8 under pressure is supplied

water for rinsing the tubers and abrasive surfaces from the processed products. From the tank 9, water through the holes 11 as a plurality of jets is ejected onto the tubers to be cleaned. Due to the coverage of the entire working chamber 3 with a network of holes 11, water jets reach almost all tubers at the same time, which ensures quick and effective flushing from cleaning products. In addition, the flow of water through the abrasive segments 7 prevents clogging of their surface, improving the quality of cleaning tubers and device performance.

Due to the ellipsoid shape of the upper and lower parts of the working chamber and the inclination of the upper part of the segments to the vertical axis, an increase in the way in which each tuber contacts the abrasive is provided (compared to the cylindrical working chamber of the prototype, where the tuber in its movement departs from the walls earlier and falls down ).

When the tubers in their movement, the abrasive wall of the working chamber move away from it and roll down, they touch the rotating core 10 and the cleaning process continues as the tubers drop down, since the departure of the tubers from the abrasive surface of the core 10 is limited by the mass of the remaining tubers.

Thus, between the case and the back surface of the abrasive segments of the working chamber a reservoir is formed into which water flows under pressure through a fitting on the side surface of the case. The segments have many through holes of small diameter through which water in the form of thin streams is directed to the tubers to be processed. The openings may be positioned obliquely to the inner surface of the working chamber in order to maximally coincide the direction of the jets. water trajectory tuberne her. This reduces the force of the unwanted repulsion of the tuber from the abrasive surface by the pressure of water supplied for washing. The supply of water to the working chamber under pressure through a plurality of holes intensifies washing, covers the entire volume of tubers being processed and prevents abrasive surfaces from clogging with cleaning products, which reduces downtime, increases productivity, and improves the quality of tubers cleaning. The abrasive lining of the inner cavity of the working chamber has smooth

Ellipsoid contours, including the upper and lower sections of the working chamber. This eliminates shock loads on the tubers and their injury, since there are no angles at the points of transition from the moving to the fixed parts of the working chamber, which is typical of the prototype. This improves the quality of peeled tubers.

In addition, the absence of abrupt transitions on the abrasive surface and the inclusion of abrasive segments into the work of the upper section, by bringing them closer to the axis of the working chamber, promotes better contact between the tubers and the abrasive and increases the contact paths, i.e. speed up cleaning.

A conical core with an abrasive surface is attached to the axis of the movable part of the working chamber. During the cleaning process, the tubers are returned from the upper zone of the chamber down and in contact with a rotating conical abrasive core. There is an additional cleaning of the tubers all the way to the lower rotating part of the working chamber, since the tuber's departure from the core is limited by the mass of the remaining tubers in the working chamber. Thus, the time of contact between the tubers and the abrasive surface increases - it improves productivity.
